Poro 2 70B Base

Poro 2 70B Base continues pretraining Meta's Llama 3.1 70B to strengthen Finnish while retaining English, code and mathematics. It is a trained derivative, not unchanged Llama hosting.

Model design and training

Continued pretraining used 165 billion tokens. The mix allocates roughly 30% each to Finnish, English and code, with 10% mathematics. Finnish material comes from FineWeb2; the other components include FineWeb-Edu, StarCoder data and FineMath. The release precedes instruction and preference tuning.Llama-Poro-2-70B-base: official model card

Practical assessment

Practical guidance. Use this larger base to study language adaptation without also changing the instruction-training method. Its parameter count affects weight memory separately from context memory. Compare short and long Finnish passages before choosing a document-processing workflow.
